Abstract

The main object of the invention is a turbomachine bearing seal device (10), able to separate an oil chamber (5) and an air chamber (6) from the turbomachine, comprising a gasket segmented seal (7) for providing the main seal of the device (10) and a support casing (14) for holding the segmented seal (7), the support casing (14) having a first groove ( 25) housing a first elastic seal (19) for centering the support casing (14), characterized in that the support casing (14) has a second groove (25) housing a second elastic seal (19) for centering the support casing (14), in particular for aligning the axis of the support casing (14) with the axis of the rotor.
